Sluice box design

Found this a few years ago, although it deals with large production sluice boxes, a lot of the design ideas are applicable to smaller boxes.  Hope someone can get some use out of it.*placerrecovery.pdf

The 51-page .pdf you have is the same as the 56-page .pdf listed below, only yours is text only. The one below is a bit easier to read...at least I think so. There are also 2 other smaller files that were put out:

The 4-page link is:
https://yukoncollege.yk.ca/downloads/Grinding_for_Gold.pdf

Another 39 page .pdf is at:
http://www.geology.gov.yk.ca/pdf/141114_Nov1014_Grinding_for_Gold_Presentation.pdf

The link to the final .pdf (56 pages) article is: http://kpma.ca/assets/files/grinding-for-gold-report.pdf

In these articles, among other things, is specific information concerning building one of these rod mills for your own use. Has been a while since I read them, but I know that the 4-page article had info that the 56-page final didn't have....that is, unless I just didn't read close enough!

Quite true and we don't use (Golden) fleece anymore.  I am curious through, is there another device that is capable of 95+% recovery in alluvial gravels and is equally effective in large mechanized operations and still works for equally well for the back packing hobbyist.

Miners are skeptical of changing  things they know works but  I think some smaller ops are coming  around to  using  Goldhog  mats  in their sluices.  Doc has worked with some ops and has proven that they  work as well or better and they are much easier to clean  up  than other systems. They are indeed  suitable for portable  sluices.

Hi .Azau covered it.Gold hog ROCKS.But if I was backpacking I would go with Keenes  mirical matt.If weight is a concern.Much lighter and works a 100 times better than any carpet or fleece out there.Luck Mcbain.
